Topcon PN-A5 Full Spectrum GNSS Antenna

The Topcon PN-A5 is a revolutionary semi-hemispherical GNSS antenna that provides unmatched signal tracking and multipath reduction.



The Topcon PN-A5 is a pin-based GNSS antenna that combines the TA-5 full spectrum GNSS antenna with a novel semi-hemispherical convex impedance groundplane and uses vertical dipoles to provide highly accurate signal tracking.

The antenna element uses an array of vertical dipoles that provides highly stable and sensitive full wave signal tracking for all GNSS signals, both existing and planned. Topcon’s new convex impedance ground plane provides minimum signal loss for satellites tracked to the horizon, while also providing improved multipath mitigation.

The PN-A5 is environmentally robust and sealed, and has improved tracking for low elevation satellites for signal tracking from the local horizon to zenith. The minimized phase center also offsets variations in vertical within GNSS frequency band.
